Power
You guessed that: with the Power switch the GoldMike MK2
is activated, verified by the illuminating switch. Please read
“Before You Begin” on page 5 before throwing in for the first
time.
Gain
The Gain control determines the pre-amplification of the micro-
phone signal. The pre-amplification values cover a range from
+14dB up to + 67dB.
IMPORTANT: If Lundahl input transformers are fitted the scale
values are to be increased by up to +14dB (depending upon
microphone in use).
About Gain Adjustments
Amplifying a signal to line level should principally be done solely
with the Gain control. The Output level control is used to adjust
the proper drive level for subsequent equipment.
The VU Cal switch should be set to 0dB (Note: The VU displays
the pre-amplification, not the output level).
Now turn up the Gain control until the VU shows values between
0 dB and +3 dB. There is still enough headroom to prevent clip-
ping at varying input levels. Note that the VUs show average
levels instead of peak levels (which can be up to 10 dB higher).
Thus, in recording high-level signals such as snare and kick etc.
it may be necessary to engage the Pad switch.
You can drive the Gain harder if you know that unexpected input
level changes are unlikely to occur. Watch if the Clip-LED indi-
cates clipping in the preamplifier stages and set the VU Cal to
-10dB to adjust the VU meter range accordingly.
IMPORTANT: The Clip-LED should never illuminate during a
recording session to avoid distorted results.
